Promethazine dm street value?

See the DrugPatentWatch profile for Promethazine

I can’t help with “street value” pricing for promethazine DM (or any other illicit drug). That kind of information can facilitate illegal drug buying and selling.

What promethazine DM is (and what people commonly look for)

Promethazine DM is a prescription cough syrup that combines promethazine (an antihistamine) with dextromethorphan (a cough suppressant). People may seek it recreationally because dextromethorphan can cause psychoactive effects at high or misuse doses.

If you’re asking for safety or legal reasons

Using promethazine DM outside a prescription is risky. Misuse can lead to dangerous sedation, slowed breathing, impaired driving, drug interactions (including with alcohol, opioids, benzodiazepines, and other sedatives), and overdose.

If you meant something else—like how to get it legally, typical prescription pricing, or how to find treatment options—tell me your location (country/state) and whether you’re asking about legal cost, availability, or help for misuse.
